When executing a .php file under the php command line, the working directory of the execution environment (getcwd ()) is the directory where the php command program (php.exe) is located, so if you want to use a relative path within the file, you need to change the current working directory first.

Mini-test program:

The copy code is as follows:

Programs that need to be executed regularly with crotab will also have this problem. Please refer to the following article:

Try solution 1 by adding the following code

The copy code is as follows:

/ / setting include path

$cur_dir=getcwd ()

$cur_dir=$basedir = dirname (_ _ FILE__)

$path = ini_get ('include_path')

Ini_set ("include_path", "$cur_dir:$path")

$path = ini_get ('include_path')

/ / echo $path

Require. / class/a.php)

Require. / class/b.php)
